Federal courts have determined the “supremacy clause” extends all rights granted under the Constitution to all citizens and takes precedence over all state and local law to the contrary. It has been used to impose Federal Law with respect to voting rights and other civil liberties. No damn reason why it should not apply to the Second Amendment.
It has also been used to ban the bible and prayer in schools, overturn state anti-abortion laws, and force hiring quotas and so-called "gay rights". This unconstitutional doctrine invented by the federal courts has lead to a parade of horribles, the deaths of tens of millions of unborn, and threatens to extinguish individual rights - the very opposite of the constitutional presumption of our pre-existing rights to Life, Liberty and Free Pursuits, of the the Declaration of Independence.
There is no constitutional support for federal courts' determining that the feds have authority to enforce all rights. In fact this invented doctrine expressly CONTRADICTS the Ninth and Tenth Amendments of the Constitution. The ONLY legitimate federal power is that which is delegated to them by the Constitution from the states and the people. Thus, if it is not a delegated power enumerated mostly in Article I, Section 8, it is NOT a federal power.
Stop supporting the death and destruction of the unconstitutional decisions and acts (AKA TYRANNY) of the federal government.
